I stopped at Blizz last night before the Kathy Griffin show at the Mirage. It's very handy and the frozen yogurt is quite good. I did a mixture of peanut butter and coconut and put some toppings on.
The problem with this outlet is you're paying Strip prices ($.69) an ounce. Blizz is more expensive than other yogurt shops, but this is over the top. In spite of the cost, the yogurt was very good, The people running the register were quite efficient and friendly.
The location was very clean and bright. I was surprised by the lack of flavors. Most yogurt places have two or four more flavors. This seemed to be lacking. The same goes for the toppings although they did have some I hadn't seen at other places.
Having had a late lunch, this was a perfect dinner.
